SUPPLY-REGULATOR FOR WATER-CLOSET BOWLS.

SPECIFICATION forming part of Letters Patent No. 594,886, dated December 7, 1897.

Application filed July 3, 1896. Serial No. 597,934- (No model.)

To all whom it may concern.-

Be it known that 1, JOHN MADDooK, a citizen of the United States, and a resident of the city of Trenton, county of Mercer, and State of New Jersey, have made certain new and useful Improvements in Supply-Regulators for VVater-Oloset Bowls, of which the following is a specification.

The object of my invention is to provide an improved regulating device by which the relative proportions of the water descending from the supply-tank to flush the bowl or to aid the siphonic action of the closet may be accurately regulated.

Owing to the great difference which exists in the height at which a tank is placed relatively to the bowl, and especially in view of the requirements of modern plumbing in that regard, it has become a serious inconvenience to employ a closet in which by a fixed and unchangeable arrangement of the bowl in the pottery a fixed distribution of water is made without regard to the height of the tank. It is obvious that the less fall there is to the water entering the closet through the supplypipe the less pressure can be derived from a given quantity of water. To adapt the closet tothis variation in pressure and to make the best possible distribution of the supply, in View of the requirements of the particular location of the closet, is the object of my invention.

To this end my invention consists in providing the earthenware closet-bowl with an easily-adjusted regulator inserted therein and adapted to close or partially close the opening into one of the channels thereof connected with the supply-pipe, whereby any desired proportion of said supply can be allowed to pass through or be excluded from said channel.

One form of my invention is shown in the accompanying drawings, in which- Figure 1 is a vertical section of so much of an earthenware bowl as is necessary to illustrate my invention. Fig. 2 is a horizontal section on line 2 2 of Fig. 1.] Fig. 3 is a detail of part of the regulating device.

Same letters indicate similar parts in the different figures.

A is a portion of a siphon water-closet bowl of usual construction, except as hereinafter specified.

B is the usual inlet, to which the supplypipe leading from the tank is secured in the usual way.

O is the passage leading to the jet which starts the siphon. This passage communicates with the inlet 13 through the opening a.

D is the crown of the siphon.

E is the flushing-rim.

The flushing-rim receives water from the channel 0 through the circular opening I). The amount of water allowed to enter through said opening is controlled by the regulator about to be described, the insertion of which in an earthenware closet-bowl constitutes my invention. This regulator is preferably made of metal and consists of the screw-threaded stem F, terminating in the disk G, which is preferably of circular shape slightly larger than the aperture b. Its lower surface is also preferably slightly convex.

H is an internally-threaded spud through which the screw-stem F turns and is provided with the lugs c c, which are adapt-ed to turn under the overhanging walls of the recess d in the earthenware. The projecting end of this spud is externally screw-threaded and meshes with the nut I, by which it is held tightly in place after insertion in said recess. a J is a jam-nut, which when turned into position against the larger nut I, as shown, holds the stem F with sufficient force to prevent its being unscrewed by the action of the water, but not with sufficient force to prevent its being released, when desired, by unscrewing from the outside.

It is obvious that the amount of water admitted to the flushing-rim E through the opening 12 can be diminished to any desired degree by causing the plate G to approach said opening and shut off any desired proportion of its area.

The advantages of this regulator will, I think, be sufficiently obvious without further explanation.

I claim-- The above-described regulator forwater= closet bowls and similar articles which consists of the Combination of a bowl having a from the exterior into greater or less proxrecess for receiving the supply-Water from imity to said first aperture, whereby the supthe supply-pipe, an aperture leading from ply of water to the flushing-rim is regulated.
